DOUGH-KNEADER= SPECIFICATION forming part of Letters Patent No. 400,187, dated March 26, 1889.

To all whom it may concern:

Be it known thatI, JOHN H. BOWERS, a citizen of the United States of America,resid ing at Mound City, in the county of Holt and State of Missouri, have invented certain new and useful Improvements in Dough-Kneaders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, which form apart of this specification.

My invention relates to certain new and useful improvements in dough-kneaders, the object being to provide a device whereby the dough may be rolled, worked, or kneaded, said device consisting, essentially, of a longitudinally-moving board having rack-bars secured thereto, a vertically-adj ust-able roller located above said board vand provided with gearwheels connected by intermediate pinions to the rack-bars, the aforesaid roller having a shaft and operating crank-handle, which shaft is supported in vertically-adj ustable bearings, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying` drawings, Figure l is a perspective view of a dough-kneader constructed in accordance with my improvement. Fig. 2 is a longitudinal section.

A refers to the side pieces, which constitute the frame of the apparatus, they being rigidly bolted or otherwise secured to the top of a flour-chest or table. The lower portions at the corners of these side pieces have formed thereon blocks or bearings a a, with perforations for the reception of gudgeons, which support the rollers B B, said rollers having central circumferential recesses, h.

On the inner edges of the side frames, A, between the blocks a c, are formed webs c, through which the connecting' bolts or screws pass for securing said side pieces rigidly to a suitable support. The side pieces, A, extend upwardly and are shaped substantially as` shown, they being provided with extended or projecting portions d d, to which are secured stub-shafts, which carry pinions e e. These frames are also provided with segmental slots D D, and the outer edges of the frames adjacent to these slots have teeth f formed therein.

Between the slots D D and the shafts of the pinions c are pinions through which pass stubshafts e', which hold in place pinions g and the ends of the bifurcated'levers G.

Over the rollers B B and supported thereon is a dough-board, F, to the under side of which is secured a guide-strip, j", which lies in a central recess formed in said rollers. The

edges of this dough-board F have secured thereto rack-bars h h, which engage with the pinions e, these pinions meshing with the pinions g, whichrotate freely on the stub-shafts c.

The roller H is rigidly mounted on a shaft, I-I, and to said roller upon the shaft, so as to move therewith, are secured cog-wheels I, which engage with the pinions g. The shaft H passes through the side pieces of the bifurcated levers G G, and also through the segf mental slots D, and these levers G carry spring-pawls which engage wi th the teeth f, so as to hold the roller H in position, and by adjusting these levers the distance of the roller from the board F may be varied.

The operation of my invention is-as follows: The dough to be kneaded is placed upon the board F, and as the crank-handle is turned said board carrying the dough is passed under the roller, the direction of the rotary movement of the crank-handle being changed as the end of the board is reached,thus causing the board to reciprocate as the dough is worked. The roller H can be depressed by releasing the spring-pawls and depressing the levers, so as to further compress and work the dough upon the kneading-board.

I claiml. The combination, in a dough-kneader, of the side frames carrying pinions g and c, and having raclcteeth in one part of the edge thereof, bifurcated levers G G, pivoted to said frame, said levers forming bearings for a crank-shaft carrying a geared roller, and spring-actuated pawls adapted to engage the rack-teeth on the side frames for adjusting the bifurcated levers and roller, the said frames having slots through which the rollershaft passes, and a kneading-board having IOO rnek-teet-h, the paris being orgnnized suhstzmr vnlly :rs shown7 and for The purpose setorth.

i i r io Said crunk-shaft operating to reciprocate the 1 nending bed and :uhrpted to have ntempermy stationary :uljustnnent Toward or :1n/ary lroxn sind hed by means of the levers, subsnnthllly as (hlserihm'l.
